FBT will not applicable in following two situation:
1) Any expenditure on, or payment for food or beberages provided by the employer to his employees in office or factory.
2) Any expenditure on or payment through paid vouchers which are not transferable and usable only at eating joints or outlets.
So there are no condition of holiday or not. If the expenses made in office or factory premises or by non transferable vouchers then it will not be under the perview of FBT. And I believe department has a clear view that if any food expenses by employer in office for employees then it will not be taxable under FBT .... and holiday is not a point to be considered here.
